A Stone of Mass 5g was lowered into a solution of turpentine of relative density 1.6. lf the relative density of a Stone is 2.0 . calculate the mass in kilograms of the turpentine displaced by a Stone.​

Why does the input force have to be greater than the force needed to lift the bale?

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
